Rust-Oleum products no longer contain whale oil, instead using resins derived from alkyds, polyurethanes, epoxies, latex, etc. Rust-Oleum remained a family-owned company until 1994, when it was acquired by current owner RPM International Inc. [2] In 2015, the company reached one billion dollars in revenue. [3]
Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.Its manufacture involves the synthesis of polyurethanes having carboxylic acid functionality or nonionic hydrophiles like PEG (polyethylene glycol) incorporated into, or pendant from, the polymer backbone.

Polyurethane – Polyurethane floor finishes were first introduced around 1942. Water-based urethane is harder than oil-modified polyurethane and is much safer for the user. Within both categories there are many variations and other names used to describe the finish. They have very different refinishing and maintenance requirements.
